I have been asked how my car sounds inside the cabin and outside.As you may have read I have the Stainless Works coated headers,hi flow cats and Corsa exhaust.I can tell you that it is MINIMALLY louder than stock inside while driving but still very comfortable and easy to have a conversation.Outside at WOT it sounds like an F1 car(awesome).I highly recommend this combo.There is absolutely NO drone thanks to the Corsa.It sounds very loud in the video clip that is posted above and I believe that is just because of the recording.It is in reality not that loud .

People don't seem to understand that you get what you pay for. If you take your car to an exhaust shop and pay $200 to have a knucklehead who learned to weld in 5 minutes hack a Flowmaster onto your car it's going to sound like shit! Corsa is worth every last cent.

No Sun roof (moon roof) Just the strip?? Looks good, and sounds good!
Did you have to do the exaust because of the upgrades in the engine??
Or just cuz
What did you add to it... cam specs...etc and if you dont mind how much did it cost you?....ball park if you like.
Not sure if I want to do my ZL1 or keep it stock..I meen around 500 stock to 600...it sounds worth it but was it?

so 720 RWHP is what 860 to 880 to the crank? KDI has a ZL1 with the same specs.
